To {t/Z whom t may concern.-

Be it known that I, WILLIAM S. STUCKEN- BERG, a citizen of the United States, residing at Indianapolis, in the county of Marion and 5 State of Indiana, have invented certain new and useful Improvements in Box-Forming Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others 1o skilled in the art to which it appertains to make and luse the same.

My invention relates to improvements in mechanism for making boxing material. One of its objects is to provide mechanism by x5 means of which slats or continuous sheets of veneer may be bound with metal strips to f form the siding for boxes.

Another object is to provide mechanism by means of which engaging lugs are stamped 2o up from the metal strips and strips and slats or sheets immediately fed through the machine, Whereby the lugs are automatically driven into the slats and clenched, binding the Whole into sections suitable for forming 25 the siding of boxes.

' Anotherobject is to provide mechanism for automatically and continuously feeding the material and carrying on the above-named operations.

automatically and independently controlling t-he feed of the stamping mechanism to deliver the stamped metal as required to the driving and clenching mechanism.

Anotherobject is to provide mechanism automatically controlled to cut the continuous sheet of box siding into sections of the desired length and also means whereby the cutoff mechanism may be set to automatically 4o cut off sections of any desired length.

My invention also further consists in several detail combinations and devices whereby the general result is facilitated, all of which will be more fully set forth in the description 45 of the accompanying drawings, forming part of this specification, in Which- Figure l is a vertical section through my improved mechanism on line 5c of Fig. 3.

A represents the frame of the machine. B represents the mechanism for stamping lup the lugs l from the metal strips 2.

on shaftfand normally held so as to trip the dog 4 and prevent it'from entering the notch c' in the clutch c. Y When pressure is brought to bear upon the cross-bar 5 through the tightening of the metal strips resting thereon, the lever F is drawn out of the path of the dog 4,

allowing the dog to catch the notch in the' clutch e and drive the rolls to feed in more of the strips.

This stamping mechanism is independently driven and is speeded some- Wbat faster than the remainder of the mechanism, so as to thus automatically supply the stamped strips as fast as and only as required.

This stamping mechanism may beof any approved 'pattern which can be automatically controlled,as described,to supply the stamped strips to the remaining mechanism as required.

From the stamping mechanism the IOO strips 2 are fed over the rolls G and brought in contact with the slats H, which slats are fed consecutively from a hopper I by means of chain belts K, passing oversprocket-wheels 7l; on the respective shaft-s L M. The alternate links of this belt are provided With spurs 6, which catch the edge of the bottom Slat 3S they pass and feed the slats forward.

7 represents a rod, to which guides 8 are secured to guide the strips 2 cent-rally beneath the rolls G.

N represents a shaft carrying a series of rolls P, enacting with the rolls G, and between which and the rolls G the slats and bindingstrips are fed.

9 represents plates resting beneath the slats in frontof the rolls P to support the slats while the lugs 1 are being driven through the slats, slots or grooves 10 being cut in these plates, so that the points of the lugs may pro.- jeet through the slats without being bent. When the projecting points of these lugs come in contact with the faces of the rolls P, they are bent overor clenched, as indicated in Fig. 2. The faces of the rolls P are preferably curved or crowned in order to clench the lugs well into the faces of the slats.`

In order that the rolls G may exert a yielding pressure and accommodate any inequality in the thickness of the slats, the shaft g is mounted in boxes, which are supported upon studs 11 and held in place by means of springs 12 and lock-nuts 13. The upper ends of the studs are connected by means of a cross-bar 14.

15 represents plates adjustable upon the cross-bars 16 17 to support the under sides of the chains K in feeding the slats forward from the hopper. The plates 9 are also secured to and adjustable upon the cross-bar 17, and the sprocket-wheels 71", and rollers G P are all adjustable upon their respective shafts, so as to enable slats of different lengths to be e1nployed.

18 represents guideways for the ends of the slats, also adjustable on the cross-bars 16 17.

After passing the rolls G P the slats are lifted from the chain suflciently to clear the teeth 6 by means of disks 19 on shaft M, as shown in Fig. 1, and are then fed between the shear-blades R R. and out upon the table 20.

The shafts g N M are driven through the following instrumentalities: Q represents an independently-driven pulley similar to pul.- ley E, provided With a dog 4 and mounted loosely on the shaft N. 2l represents a clutch similar to e, rigid upon shaft N. 22 represents a tripping-rod operated by a treadle 23 to throw the dog 4', and thus stop or start the feed. Upon the opposite end of the shaft N is a gear 24, driving shaft g through gear 25 and also driving an idlergear `26, which in turn drives gear 27 on shaft M. The rod L does not revolve, but is adjustable to or from the shaft M by means of bolts 28, passing through slots 29 in the frame A. The sprocket- Wheels k journal on the rod L and are held to the adjusted position by collars 30.

The lower-shear-blade is driven at. appropriate intervals to cut the sheet of boxing material into sections of the desired length in the following manner: S represents a shaft carrying eceentrics 31, which reciprocate the shear-blade R through the connecti ng-rods 32. Upon one end of shaft S is an independently-driven pulley T, similar to pulley E and carrying a dog 4". A clutch 33 similar to clutch e secured to the shaft S. 34 represents a sprocket wheel mounted on and driven by shaft M. 35 represents a sprocketwheel loosely journaled on shaft S. 36 represents an idler sprocket-wheel mounted upon the adjustable stud-shaft 37. 38 represents a chain belt passing over the wheels 34 35 36 and provided with one or more curved links 39. 40 represents a tripping-lever pivoted at 41 to the frame of the machine. One end of this lever is armed with a roller 42, which is pressed upon the chain by means of the spring 43. The opposite end of the lever is provided with a trip 44, normally engaging and holding the dog 4" out of engagement with the clutch 33. When the curved link 39 comes opposite the roller, the lever moves, releasing the dog 4", which causes the shaft S to make one revolution and sever a section of the boxing. By the ltime the shaft S has completed one revolution the curved link has passed the roller and the trip 44 acts again. In order to cut longer or shorter sections, one or more links are added to or taken from the chain 33 and ,the stud-shaft adjusted to take up the slack in the chain.

Having described imy invention, what I claim isl 1. In a box-forming` machine the combination of a series of rolls over which the metal strips are fed; anvil-plates supporting the slats while the lugs of the metal strips are be ing driven; and a series of clenching-rolls in the rear of said plates for bending the ends of the lugs, substantially as specified.
